A great first step into the world of self sufficiency is container gardening. The cost is relatively low, the returns amazing.
So where to begin?
Let’s start with the container. Small circular pots about 8cm (3 inch) in diameter are good. Plastic, ceramic, manufactured for purpose, fruit tins or found objects all work. Begin where you are and use what you have at hand. Potting soil can be picked up cheaply. Soil dug from garden will work but it will give you drainage problems most times but you might be lucky and have suitable soil. It’s all an experiment so have fun.
